Seems quite even to me :)

Seriously, the ability to negative-index strings and arrays like that
is a breath of fresh air compared to traditional compiled languages.
I see no need to improve on it.

I rather doubt that's going to happen.  When you execute str[3..7],
the 3..7 isn'y arbitrary syntax, it's a Range object.  If Range
objects were allowed to be unbounded, then fine.  So the question
really becomes, should Range objects allow unbounded ranges?

Write a String#substring method if you like.
